Redaelli代号Red1之6×36类独立钢芯海工钢丝绳,直径40~140 mm,共65个规格,用抗拉强度给钢丝绳赋级。研究表明:借用普通直径钢丝绳破断拉力计算公式,该钢丝绳破断拉力系数随绳径增大而明显降低,钢丝绳破断拉力不与绳径平方成正比;钢丝绳破断拉力与绳径间存在可拟合的数学关系式,破断拉力可拟合成绳径的二次函数或三次函数,且采用三次函数形式时由拟合关系式求得破断拉力与给出值对比误差更小;视钢丝绳破断拉力等于系数与绳径平方之积且拟合关系式选择三次函数形式,破断拉力系数随绳径增大而减小,二者间存在十分显著的线性关系,与BS 302/P7—1989、ISO 8369—1986及EN 12385-4:2002等给出钢丝绳破断拉力计算公式之反映一致。
Redaelli codenamed Red1 6 × 36 independent steel core offshore wire rope, diameter 40 ~ 140 mm, a total of 65 specifications, with the tensile strength of the rope grading. The research shows that the formula of breaking tensile force of ordinary diameter steel wire rope is used, the breaking coefficient of steel wire rope decreases obviously with the increase of rope diameter, and the breaking force of steel wire rope is not proportional to the square of rope diameter. There exists a fitting math between wire rope breaking tension and rope diameter Relationship, breaking force can be fit into the quadratic function or cubic function of the rope diameter, and the use of cubic function form obtained by fitting the relationship between the breaking force and the given value of the error is smaller; depending on the rope breaking force is equal to the coefficient and The product of the square of the diameter of the rope and the square of the fitting formula is selected as the cubic function form, and the breaking coefficient of the wire rope decreases as the diameter of the rope increases. There is a very significant linear relationship between them and BS 302 / P7-1989, ISO 8369-1986 and EN 12385-4: 2002 gives the wire rope breaking tension calculation formula is consistent.
